Generate Video Access token (JWT) with Twillio Go SDK

Question

I am failing to create an Access Token for the Twillio Video Product with the golang SDK In the docs there is golang sadly not mentioned

Does anyone of you know how I can create the required access token?

The JWT package mentioned in the examples of the other languages can not be found in the Go SDK.

This might help although this is quite old: https://www.youtube.com/watch?v=mTd3hHUy9OU, the api may have changed in the meantime. — Sazid, Jun 04 '21 at 08:29

I found that it is just not possible to do it with the default go SDK. I did follow the instructions on https://www.twilio.com/docs/iam/access-tokens and build the JWT myself. Maybe someone will find the solution handy:

package main

import (
    "encoding/json"
    "fmt"
    "github.com/dvsekhvalnov/jose2go"
    "log"
    "time"
)

func main() {
    accountSid := "XXX"
    keySid := "YYY"
    keySecret := "ZZZ"

    username := "Simon"
    roomName := "SimonsRoom"

    now := time.Now()

    type JWTPayload struct {
        Jti                    string `json:"jti"`
        Issuer                 string `json:"iss"`
        Subject                string `json:"sub"`
        CreationUnixTimestamp  int64  `json:"iat"`
        NotBeforeUnixTimestamp int64  `json:"nbf"`
        ExpiresUnixTimestamp   int64  `json:"exp"`
        Grants                 struct {
            Identity string `json:"identity"`
            Video    struct {
                Room string `json:"room"`
            } `json:"video"`
        } `json:"grants"`
    }

    payload := JWTPayload{
        Jti:                    fmt.Sprintf("%s-%d",keySid,now.UnixNano()),
        Issuer:                 keySid,
        Subject:                accountSid,
        CreationUnixTimestamp:  now.Unix(),
        NotBeforeUnixTimestamp: now.Unix(),
        ExpiresUnixTimestamp:   now.Add(23*time.Hour).Unix(),
        Grants: struct {
            Identity string `json:"identity"`
            Video    struct {
                Room string `json:"room"`
            } `json:"video"`
        }{
            Identity: username,
            Video: struct {
                Room string `json:"room"`
            }{
                Room: roomName,
            },
        },
    }

    payloadByte, err := json.Marshal(payload)
    if err != nil {
        log.Fatal(err)
    }
    token, err := jose.SignBytes(payloadByte, jose.HS256, []byte(keySecret),
        jose.Header("cty", "twilio-fpa;v=1"),
        jose.Header("typ", "JWT"),
        jose.Header("alg", "HS256"),
    )
    if err != nil {
        log.Fatal(err)
    }

    fmt.Println(token)
}
